Qhov sib txawv tseem ceeb ntawm pigments thiab dyes yog lawv daim ntawv thov.Dyes feem ntau yog siv rau textiles, thaum pigments feem ntau tsis yog textiles.
Yog vim li cas vim li cas pigments thiab dyes sib txawv yog vim dyes muaj ib tug affinity, uas tseem hu ua directness, rau textiles thiab dyes yuav adsorbed thiab tsau los ntawm fiber ntau molecules;Pigments tsis muaj affinity rau tag nrho cov khoom xim, feem ntau yog nyob ntawm resins, adhesives, thiab lwm yam rau xim cov khoom.Dyes qhia txog pob tshab thiab feem ntau muaj qhov ci zoo;Pigments hais txog kev npog cov khoom thiab feem ntau muaj kev ruaj ntseg zoo.
Nov yog peb qhov sib txawv ntawm cov pigments thiab dyes:
Thawj qhov sib txawv ntawm pigments thiab dyes yog txawv Solubility.Qhov sib txawv ntawm cov pigments thiab dyes yog lawv solubility.Raws li paub zoo, pigments yog insoluble hauv kua, thaum dyes tuaj yeem ncaj qha soluble hauv cov kua xws li dej, kua qaub, thiab lwm yam.
Qhov thib ob qhov sib txawv ntawm cov xim thiab cov xim dyes nyob hauv thier Txawv Xim Txoj Kev.Pigment yog cov hmoov xim xim uas yuav tsum tau nchuav rau hauv cov kua ua ntej xim.Txawm hais tias nws yuav tsis decompose thiab yaj hauv cov kua, nws yuav sib npaug sib npaug.Tom qab nplawm tusyees, cov neeg siv tuaj yeem pib xim nrog txhuam.Txoj kev dyeing ntawm dyes yog nchuav rau hauv cov kua, tos kom lawv yaj tag rau hauv cov kua, ces muab txhuam rau hauv cov kua rau dyeing, thiab ces tshem tawm cov txhuam hniav ncaj qha thiab siv cov xim.
Qhov kawg qhov sib txawv ntawm pigments thiab dyes yog txawv siv.Tom qab nyeem ob qhov sib txawv saum toj no, cia peb saib qhov sib txawv kawg, uas yog daim ntawv thov.Pigments yog siv nyob rau hauv coatings, inks, luam ntawv thiab dyeing, thiab lwm yam;Dyes, ntawm qhov tod tes, feem ntau yog siv rau hauv cov ntaub ntawv fiber ntau, tshuaj engineering, lossis kho kom zoo nkauj hauv tsev.
Cov neeg siv khoom tuaj yeem xaiv cov xim raws nraim lossis xim xim thaum lawv yuav.
